The average running speed of a human can vary depending on factors such as age, fitness level, and distance covered. Generally, for an average adult, the typical running speed is around 8 to 12 kilometers per hour (kph) or 5 to 7.5 miles per hour (mph). However, it's important to note that individual capabilities can differ significantly. Trained athletes can achieve much higher speeds, with top sprinters reaching speeds above 37 kph (23 mph) in short bursts.
